I belive that the creators should look into Taxation of Territories. i personally am a very finanical type of guy, i enjoy being on the top 5% of richest players no matter what game i play.I would like to be able to build idk lets say a mountain city, and have a pass there, for people who want to transport armies, like a neutral faction, that will trasnsport goods and armies for a sum.

Ofcourse a nation could simply attack you, take your terriorty, but if you have a massive empire, and the mountain yours, that war would rage for days if not weeks, considering renegade armies would fight and resist control, lamost like a mountain empire, holding off, baricadeing, etc. until reinforcments arrive from other allied factions, and then the mountain can be retake, this would have to be a heavily armed/fortified city, with power that is unimaginable.

It would be good to be able to build an economic empire and not have to expand through conquering, focusing your military on more defense. how about turning your city into a trade hub where the surrounding groups send all their trade through and you profit from it.

I like the idea of tax and having a powerful economic nation, it reminds me of Terry Pratchett's Ankh-Morpork where rather than have massive powerful armies, they would just have every other nation so much in debt that they owned all their armies weapons and armour.
